Answer:

The slope of this line is 1/2.

Step-by-step explanation:

You have to pick any two coordinates from the line. So I will pick (2,0) and (4,1). Then you have to use gradient formula :

$m = \frac{y2 - y1}{x2 - x1}$

Let (x1,y1) be (2,0),

Let (x2,y2) be (4,1),

$m = \frac{1 - 0}{4 - 2}$

$m = \frac{1}{2}$

Answer:

Confidence interval: (1760,1956)

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 81

Sample mean =

$\bar{x} = 1858 \text{ kWh}$

Population standard deviation =

$\sigma = 450 \text{ kilowatt-hours}$

Confidence Level = 95%

Significance level = 5% = 0.05

Confidence interval:

$\bar{x} \pm z_{critical}\displaystyle\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

$1858 \pm 1.96(\displaystyle\frac{450}{\sqrt{81}} ) = 1858 \pm 98 = (1760,1956)$
